Hot air gun ,low heat setting, has removed all gum based stickers that I've

chemical welding process into the underlying plastic over time

I damaged a laptop LCD cover while using a hot air gun to remove some
stickers. Hot air works great on metal surfaces (i.e. removing bumper
stickers and pinstriping from automobiles), but I haven't done so well
when I tried it on a laptop. My guess(tm) is that there's
insufficient difference in temperature between where the adhesive
melts, and where the plastic begins to melt.
